[0022] The following will be combined with the appended examples in the present utility model Figure 1 ~Attached Figure 3 , the technical scheme, structural features, objectives achieved and effects in the embodiments of the utility model are described in detail.

[0023] It should be noted that the drawings are in a very simplified form and use non-precise proportions.

[0024] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0025] The utility model provides a tail gas reaction chamber for a tail gas purification device, wherein the tail gas reaction chamber receives tail gas and processes it;

[0026] The exhaust gas purification device is a device used to purify exhaust gas generated in industry (such as metal processing equipment), and the exhaust gas contains a large amount of sulfide, combustible gas, harmful gas, etc.; the exhaust gas reaction chamber is arranged in the exhaust gas purification device as a specific reaction space for exhaust gas combustion.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, the tail gas reaction chamber comprises:

[0028] The combustion chamber 7 forms a combustion space inside for the exhaust gas to burn;

[0029] The medium cavity 6 is arranged around the outside of the combustion cavity 7, and a gap is arranged between the inner wall of the medium cavity 6 and the outer wall of the combustion cavity 7 to form a closed cavity 8 that can accommodate the medium; wherein the medium arranged in the cavity 8 is a gas or liquid with high thermal conductivity, and then when the tail gas reacts in the combustion space and generates a large amount of heat, the medium conducts the temperature in the combustion space to the outside of the tail gas reaction chamber, thereby achieving efficient cooling of the combustion space and preventing the equipment from being damaged due to overheating; wherein, the combination of the combustion cavity 7 and the medium cavity 6 can adopt a columnar structure with a square, circular or other cross-section, or a spherical structure, etc. according to actual needs;

[0030] A plurality of air inlets 2, any of which penetrates through the side walls of the medium chamber 6 and the combustion chamber 7, and communicates with the combustion space, receives the exhaust gas and provides a flow path for the exhaust gas to enter the combustion space; it should be noted that when the air inlet 2 penetrates through the side walls of the combustion chamber 7 and the medium chamber 6, it should be noted that the sealing should be ensured to prevent the medium in the cavity 8 from escaping due to incomplete sealing caused by the opening of the air inlet 2; specifically, a sealing component can be provided between the two walls of the combustion chamber 7 and the medium chamber 6 at the air inlet 2 to ensure the sealing of the cavity 8; for example, a sealing ring adapted to the air inlet 2 can be provided to ensure that the medium does not escape due to the opening of the air inlet 2;

[0031] The air outlet 1 is opened through the surface of the combustion chamber 7 and the medium chamber 6, and is used to discharge the treated exhaust gas; it should be noted that the setting of the air outlet 1 cannot conflict with the air inlet 2; similarly, when the air outlet 1 passes through the side walls of the combustion chamber 7 and the medium chamber 6, it is also necessary to pay attention to the sealing; specifically, a sealing component can be provided between the two walls of the combustion chamber 7 and the medium chamber 6 at the air outlet 1 to ensure the sealing of the cavity 8; for example, a sealing ring compatible with the air outlet 1 can be provided to ensure that the medium does not escape due to the opening of the air outlet 1.

[0032] In addition, the combustion chamber 7 and the medium chamber 6 are provided with an upper opening and a lower opening at the top and bottom;

[0033] An ignition device is arranged above the upper opening for burning the exhaust gas; similarly, because the upper opening passes through the top of the combustion chamber 7 and the medium chamber 6, attention should be paid to the sealing; specifically, a sealing assembly is arranged between the two walls of the combustion chamber 7 and the medium chamber 6 at the ignition device to ensure the sealing of the cavity 8; for example, because the ignition device will form a contact profile with the upper wall of the combustion chamber 7 and the upper wall of the medium chamber 6 respectively, a sealing ring matched with the contact profile can be arranged between the two walls of the combustion chamber 7 and the medium chamber 6 to ensure that the exhaust gas and the medium will not escape due to the arrangement of the ignition device.

[0034] A collecting device is arranged below the lower opening, because a large amount of dust will be generated when the exhaust gas is burned. If it is not removed in time, it will inevitably cause problems such as incomplete combustion of the exhaust gas in the exhaust gas reaction chamber. Therefore, a collecting device is used to collect the dust and then remove it, thereby ensuring the service life of the exhaust gas reaction chamber. Similarly, because the lower opening runs through the bottom of the combustion chamber 7 and the medium chamber 6, it is necessary to pay attention to the sealing. Specifically, a sealing assembly is arranged between the two walls of the combustion chamber 7 and the medium chamber 6 at the collecting device to ensure the sealing of the cavity 8. For example, because the collecting device will form contact contours with the lower wall of the combustion chamber 7 and the lower wall of the medium chamber 6 respectively, a sealing ring that is compatible with the contact contour can be arranged between the two walls of the combustion chamber 7 and the medium chamber 6 to ensure that the exhaust gas and the medium will not escape due to the setting of the collecting device.

[0035] If in a specific application, it is necessary to set other corresponding devices above the upper opening and below the lower opening, it is also necessary to pay attention to the sealing. The corresponding sealing components can be set as described above to prevent the exhaust gas and medium from escaping during combustion.

[0036] In a preferred embodiment, the medium can be difluoromonochloromethane, difluorodichloromethane, water, etc., without limitation; however, when the combustion space operates for a long time, even a medium with good thermal conductivity will not dissipate heat sufficiently due to overheating, resulting in reduced heat dissipation effect.

[0037] To cope with this situation, the outer wall surface of the medium cavity 6 is provided with a medium inlet 3 and a medium outlet 4 connected to the cavity 8, and the medium outlet 4 is provided above the medium inlet 3; if the medium outlet 4 is provided below the medium inlet 3 or provided in parallel, the medium will leave the cavity 8 before completely receiving the heat from the combustion space due to gravity, and the expected heat dissipation effect cannot be achieved;

[0038] The medium enters the cavity 8 from the medium inlet 3 and leaves the cavity 8 from the medium outlet 4; for example, when difluorochloromethane is used, difluorochloromethane (liquid) enters the cavity 8 from the medium inlet 3, absorbs heat from the combustion space, becomes gaseous, and leaves the cavity 8 from the medium outlet 4 to achieve heat dissipation. The same is true when other media are used.

[0039] When the medium inlet 3 and the medium outlet 4 are used to realize the medium flow, it will inevitably lead to inconsistent pressures at various locations in the cavity 8; if things go on like this, the tail gas reaction chamber will be significantly deformed, reducing the service life of the entire equipment. In order to solve this problem; the tail gas reaction chamber also includes: a number of reinforcements 9, any of which penetrates the side walls of the combustion chamber 7 and the medium chamber 6, and the two ends of the reinforcement 9 are respectively arranged on the outer wall of the medium chamber 6 and the inner wall of the combustion chamber 7, thereby playing a role in reinforcing the combustion chamber 7 and the medium chamber 6; in addition, when setting the reinforcement 9, it is necessary to pay attention to the sealing of the reinforcement 9 and the combustion chamber 7 and the medium chamber 6 to prevent the medium from escaping; and it should also be noted that it should not conflict with the air outlet 1, the air inlet 2 and other components.

[0040] In a specific embodiment, the reinforcement member 9 can be a bolt, a pin, etc., which can be selected according to actual conditions.

[0041] In a preferred embodiment, in order to better fix the exhaust gas reaction chamber inside the exhaust gas purification device and prevent vibration caused by overly intense reaction in the combustion space, the exhaust gas reaction chamber also includes: a fixing seat 5 arranged on the surface of the medium cavity 6, and the fixing seat 5 is used to connect the fixed components in the exhaust gas purification device. For example, the fixing seat 5 is connected to the fixed components in the exhaust gas purification device through a connecting rod (for example, welding) to achieve a stable fixation of the exhaust gas reaction chamber.

[0042] like Figure 1 , Figure 2 .、 Figure 3 As shown, the following is an introduction to a specific embodiment:

[0043] In this embodiment, the combination of the combustion chamber 7 and the medium chamber 6 is a columnar structure with a square cross section;

[0044] The combustion chamber 7 and the medium chamber 6 are connected at the top and bottom to form an upper opening and a lower opening, an ignition device is arranged above the upper opening, and a collection device is arranged below the lower opening;

[0045] The following is an introduction to the four sides of the combustion chamber 7 and the medium chamber 6;

[0046] Each side is provided with two air inlets 2, which penetrate through the side walls of the combustion chamber 7 and the medium chamber 6 and are arranged at the uppermost position;

[0047] Among them, a side surface is provided with an air outlet 1, which penetrates through the side walls of the combustion chamber 7 and the medium chamber 6. The air outlet 1 is located below the side surface and maintains a certain distance from the two air inlets 2.

[0048] Four reinforcing members 9 are disposed on the other three sides, and the reinforcing members 9 penetrate the side walls of the combustion chamber 7 and the medium chamber 6, and the two ends of the reinforcing members 9 are disposed on the outer wall of the medium chamber 6 and the inner wall of the combustion chamber 7 respectively;

[0049] One of the sides provided with a reinforcement member 9 is provided with a fixing seat 5 and a set of corresponding medium inlet 3 and medium outlet 4 as described above, and the medium is water;

[0050] The above is an introduction to the embodiments of the present utility model.

[0051] Although the content of the utility model has been described in detail through the above preferred embodiments, it should be appreciated that the above description should not be considered as a limitation of the utility model. After reading the above content, various modifications and substitutions of the utility model will be obvious to those skilled in the art.
